IMPROVEMENT IN LAMP-CHIMNEY CLEANERS.

Specification forming part of Letters Patent No. 57.149, dated August 14, 1866.

To all whom it may concern:

Beit known that I, W. J. JOHNSON, of Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Lamp-Chimney Cleaners; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is a side view of one my lampchininey cleaners, representing the two brushes as pressed together by the spring B; Fig. 2, a similar view of the same slightly modified, representing the two brushes forced apart inside of a lamp-chimney by the grasp of the operators hand. Fig. 3 is a side view of a lamp chimney cleaner, in which the arms are made of wood and united by means of a springbow, 13. Figs. 4., 5, 6, and '7 are details, to be hereinafter explained.

Like parts are indicated by the same letters in all the drawings.

The nature of my invention consists, first, in constructing the two arms of a lamp-chimney cleaner of a single piece of wire bent into the requisite shape, whereby I am enabled to make a very strong, elastic, and durable article, and one which, owing to the smallness and elasticity of its parts, can be used in the smallest and most delicate chimneys, as well as in the largest and strongest ones, without danger of breaking them; second, in uniting the two arms A A, by means of a spring, B, whether it be formed by making a coil of the wire of which the arms are constructed, as in Figs. 1 and 2, or by a separate bow-spring, as in Fig. 3, whereby the brushes are not only sprung together, but also guided laterally without being riveted or jointed together; third, in bending one of the wire arms so as to form a loop, cl, to operate as a guide for the opposite arm fourth, in confining the materials, F, of which the brushes or cleaners are made by nipping them between a serrated plate, G, and a clasp of metal, E, the edges of which are bent down over said plate.

To enable others skilled in the art to make and use my invention, I will now proceed to describe the construction and operation of the same.

A A in Figs. 1 and 2 represent an elastic wire or rod of iron, steel, or brass, of suitable stifiness, bent into the shape required, and having a coil, B, formed in the handle end, so as to constitute a spring by means of which the two brushes or cleaners will be kept together when they are not forced apart in being used inside of a chimney.

I also propose, in some cases, to bend one of the wire-arms so as to form a loop, 61, as shown in Fig. 2, and for the object specified above; or the arms may be made of wood, and united by means of the spring-bow B, or its equivalent, fastened thereto, as shown in Fig. 3, to answer the purpose of the coil B in Figs. 1 and 2.

The brushers or cleaners F F are made of bristles, worsted, or any other suitable material in general use for a similar purpose, and are confined by means of the clasp E, which is cut out, the proper size and then struck up so as to form flanges e 6 (see cross-sections, Figs. 6 and 7 around its edge. Across this piece E thus formed the worsted or other material is placed.

Gris a serrated plate of metal, shaped as shown in Fig.5, just large enough to fit in between the flanges c 0, formed on the piece E. This piece G is then placed on over the brush material and driven into the piece E, the flangese c of which being bent down will force the said material into the proper position, as shown in Figs. 1, 2, and 6, and se curely hold it in place.

The brushers or cleaners thus formed are confined in any obvious manner to the wires or rods AA, as clearly shown in Figs. 1 and 2.

The operation of the cleaner is illustrated in Figs. l and 2, in which chimneys are represented by the dotted lines. The brushes F F being inserted either at the top or bottom of the chimney, the operator simply grasps the handles A A just below the spring B in his hand and presses them toward each other, which will obviously throw the said brushes apart, as in Fig. 2, and force them against the chimney.

Having thus described the nature and operation of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Constructing the two arms of a lamp chimney cleaner of a single piece of Wire, or 4. Oonfiningthe material of which the brush its equivalent, bent into the requisite shape, is formed by means of the serrated plate G substantially as set forth, and for the objects and clasp E, substantially as and for the purspecified. pose described.

2. Unitin the two arms A A by means of the spring 35, or its equivalent, substantially JOHNSON as and for the purpose described. Witnesses:

3. The loop or guide d, substantially as and H. A. HILDRETH, a for the purpose described. w l N. AMEs.
